Ansible inventory：组之间的继承

Question

有没有一种方法可以在组之间继承变量而不使用[all:vars]

例子：

[GROUP_A]
server-A1 
[GROUP_A:vars]
vpc_cidr="192.10.0.0/21"

[GROUP_B]
server-B1
[GROUP_B:vars]
public_cidr="{{ vpc_cidr }}" 

Answer 1

我会用子组来做，将共享变量放在父组中

[parent_group:vars]
some_var=foo
some_other_var=bar

[parent_group:children]
GROUP_A
GROUP_B

[GROUP_A]
group_a_specific_var=foobar

[GROUP_B]
group_b_specific_var=barfoo
